From 1990 to 2000 the average temperature in july in dallas was latex: 97^\circ f97 ∘ f. a researcher believes due to global warming that the average is increasing in dallas. which of the below could be the alternative hypothesis?

Hₐ = The mean temperature in Dallas in July is strictly greater than 97° F.

Step-by-step explanation:

This is the answer because the question is asking you for the "alternative hypothesis" and that means that it's basically asking for the statement that agrees with what is being said.

Since we know that a student the researcher claims that the average temperature is increasing...

Then, the answer choice we choose must signify that the temperature is ONLY increasing.

Which leads us to the

 Hₐ = The mean temperature in Dallas in July is strictly greater than 97° F.

(Emphasis on "strictly greater")

P.S - I took the test and got a 100%. Good luck! (Especially if you're a senior like me!)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

the anwser is d) 75°
